What are jointing router cutters?

Jointing router cutters are used for producing a variety of common woodworking joints.

Some jointing router cutters are capable of cutting both parts of the joint, while other types may require a few basic hand tools, or even an additional router cutter of a different kind, to shape each component required for the joint.

Design

Flutes

Most jointing router cutters have two flutes and so should produce a reasonably clean finish in materials.

Bottom cut

Most jointing router cutters do not have the bottom cut facility, as they are typically designed for routing the edge of materials.

Guides

Some jointing router cutters have a pin or bearing guide located beneath their cutting edges. Others do not have a guide, and so require a side fence, back fence, or other similar aid for them to follow.

Applications

There are several different types of jointing cutters, each for particular applications.
